No infra needed

Built-in streaming

Out of the box, you can send database changes to a webhook sink or turn on a Sequin Stream. Both offer a durable, Kafka-like stream with exactly-once processing guarantees and a simple HTTP interface.

//Sequin pushes rows to your HTTP endpoint

//Example lambda handler:

exports.order_handler = async (event) => {
  try {
    processOrder(event.data.action, event.data.record);
    return {
      //message will be ack'd
      statusCode: 200,
    };
  } catch (error) {
    console.error('Error:', error);
    return {
      //message will be nack'd & retried
      statusCode: 500,
    };
  }
};

Webhook sink

POST changes from your database to any HTTP endpoint. Built in retries and back-off.
